The stability of the engine and transmission assembly damping pad is also an important factor in selecting the damping pad planning scheme. In order to ensure that the damping pad has sufficient static load to meet the requirements of the power transmission system of the loader for its service life, the additional static load capacity must be ensured when selecting the appropriate stiffness of the damping pad. Ball valve pneumatic butterfly valve is used more and more widely, and more and more derivative products are available.
In particular, industrial ball valve shock absorbers, such as tension spring shock absorbers, shock absorbers, and fan shock absorbers, have gradually become prominent in all walks of life and are beginning to play a decisive role. The reason why ball valve pneumatic butterfly valve can be continuously developed in the footsteps of the era is that its strong development foundation and outstanding renewal potential Select the appropriate lifting pneumatic butterfly valve, including the appropriate type of lifting ball valve pneumatic butterfly valve and the correct installation load.
Fix the indicator plate of the hanger on the position corresponding to the installation load with the upper and lower positioning blocks, so that the ball valve hanger is in a rigid state and exists stably. 2. Hoisting equipment and hoisting equipment shall be confirmed carefully and there is no uncertain risk factor to ensure the safety of hoisting. 3. After the overall installation, the equipment starts to run. First check whether the positioning block exists, and then check whether the indicator board is jammed during the displacement from the installation load to the working load.
Whether there is a large displacement. 4. After entering into normal operation, check whether the displacement of the ball valve support under working load is consistent with the design. After the equipment stops running, check whether the indicator board returns to the position where the load is installed. Correct installation data can be obtained by testing the above precautions to ensure stable shock proof effect and safety of the valve. The purpose of using pneumatic butterfly valve varies according to different situations.
For example, sometimes it is to reduce the vibration stress to extend the working life of the equipment; Sometimes it is to reduce the amplitude of vibration so as not to affect other equipment due to vibration; Sometimes it is to extend the vibration period and make people comfortable (such as cars). For the vibration caused by sudden impact, the attenuation of the vibration amplitude after the pneumatic butterfly valve is adopted is much faster than that without the pneumatic butterfly valve. After using pneumatic butterfly valve for continuous seismic source, the amplitude is generally reduced.
There are various types of pneumatic butterfly valves, which can be divided into fixed type (such as base pneumatic butterfly valve) and rotary type (such as rotor pneumatic butterfly valve, bearing pneumatic butterfly valve) according to whether the position of the pneumatic butterfly valve rotates; According to the valve principle of pneumatic butterfly valve, it can be divided into elastic pneumatic butterfly valve, friction pneumatic butterfly valve, impact pneumatic butterfly valve, electromagnetic pneumatic butterfly valve, hydraulic pneumatic butterfly valve, balance pneumatic butterfly valve, etc; It is classified according to the valve materials used for pneumatic butterfly valves. It can be divided into pneumatic butterfly valve, ball valve pneumatic butterfly valve, air pneumatic butterfly valve, oil pneumatic butterfly valve, etc. For reducing XHS hanging ball valve pneumatic butterfly valve and fertilizer machinery pneumatic butterfly valve.
